The leopard coral grouper is highly-valued as a food fish and is sold in both the live and chilled reef fish food trade, centred on Hong Kong. The catching of live fish for export is an important commercial fishery in the Asia-Pacific region, currently they are primarily sourced from Indonesia and the Philippines. In Australia it is caught by ...
The sea surface microlayer (SML) at the air-sea interface is a distinct, under-studied habitat compared to the subsurface and copepods, important components of ocean food webs, have developed key adaptations to exploit this niche. [40] The ocean-spanning SML forms the boundary between the atmosphere and the hydrosphere.
A marine coastal ecosystem is a marine ecosystem which occurs where the land meets the ocean. Worldwide there is about 620,000 kilometres (390,000 mi) of coastline. Coastal habitats extend to the margins of the continental shelves, occupying about 7 percent of the ocean surface area.
Hope Spots can be Marine Protected Areas (MPA) that need attention or new sites. They are chosen for their contributions to biodiversity, the carbon sink , and important habitat. Hope Spot status is intended to alleviate the pressures human resource extraction places on the ocean by making the site higher priority to become an MPA, where ...
Plectropomus coral groupers are very important to artisanal fisheries wherever they are found and they are caught using hook and line by spear fishing and trapping, however they are a frequent cause of Ciguatera poisoning among consumers of their flesh.
The oligotrich ciliate has been characterised as the most important herbivore in the ocean. The second trophic level (primary consumers) is occupied by zooplankton which feed off the phytoplankton. Together with the phytoplankton, they form the base of the food pyramid that supports most of the world's great fishing grounds.

The hadal zone, also known as the hadopelagic zone, is the deepest region of the ocean, lying within oceanic trenches. The hadal zone ranges from around 6 to 11 km (3.7 to 6.8 mi; 20,000 to 36,000 ft) below sea level , and exists in long, narrow, topographic V-shaped depressions.
